Pricing the shipment…
It reads the whole tariff
Third-country duty is the easy part. The engine also reads anti-dumping, countervailing and safeguard duties, and origin-gates them, so a Chinese e-bike owes its 62% anti-dumping duty and a Vietnamese one doesn't.
It won't quote a false zero
Champagne's duty is charged per hectolitre, not as a percentage; printed books are zero-rated for VAT. A tool that only handles percentages shows £0 or a flat 20%. This one says what is actually owed.
Every figure is sourced
Each rate is pulled from the UK Trade Tariff at quote time and cited on screen. Nothing is cached to a stale number, and nothing is invented to look precise.
Run it on your own shipment.
The quote tool takes your goods value, weight and commodity code and returns the same sourced landed cost, with the customs paperwork and compliance screening attached.
